ADDING AND LISTING MACHINE.

Specification of Letters Patent.

Patented Dec. 29, 1908.

Application filed March 21, 1908. Serial No. 422,503,

ToaZZ whom it may concern:

Beit known that I, Jnssn G. VINCENT, a citizen of the UnitectStates, residing at De troit, in the county of Wayne and State of 'Michigan, have invented certain new and useful Improvements in Adding and Listing Machines, of which the follpwing is a specification.

In machines of this character it is common to employ a series of spring-actuated hammers to do the printing and to provide fol automatically tripping off hammers from left to right for the purpose of printing ciphers in decimal places of any amount where no digits occur. It is also common practice to interrupt the tripping off of hammers when the machine isto be used for simultaneously printing two or more separate Reference may be had to the (3003-11 Patent No. 825,205, July 3, 1906, which shows an adding and listing machine of the well-known Burroughs type (see Burroughs Patents Nos. 504.963 and 505,078, September 12, 1893) modified to provide for interrupting the automatic tripping of hammers at will. Such a machine is commonly termed split and normal because of its capability for operating either with all of the hammers related for the automatic tri ping from left to right or operating in tie so-called split or divided state so that ciphers will not be printed between items or amounts of separate col-. umns. The Gooch invent-ion provides for locating the point of split variously but not for changing the location at will by the user of the machine through manipulation of devices on the exterior of the machine though this latter expedient has heretofore been practiced in what is'known as a vari able split and normal machine.

The present invention relates to this lastmentioned advanced type of adding and listmg machine and involves a new and simplified mode of arriving at the desired result which gives opportunity for considerably reducing the number of component parts in the variable split and normal mechanism and-also facilitates the assembling of parts,, besides roviding a construction which is thorouglily reliable.

-Withsuch objects in view the invention consists-in certain novel features of cpn- [struction and combinations of parts the essential elements whereof are recited in the appended claims and a preferred form of embodiment of which is clearly illustrated in the accompanying drawings and described in detail hereinafter.

Of said drawings Figure 1 represents in" sectionalized right side elevation a sufiicient portion of an adding and listing machine of the well-known Burroughs type having embodied in it the resentinvention, to show the relation of the latter to the regular parts of the machine; Fig. 2 is a "fragmcntary top plan view of the machine;.

Fig. 3 is a left side elevation. partly in section of the particular portion of the machine where the present invention takes effect, this view representing the relation of parts when the so-called split has been established at a certain point and the operating handle of the machine has been drawn forward; Fig. 4 is a similar view illustrating the changed effect when the machine is normal or operating without a split; Fig. 5 is a front elevation of that de art'- ment or section of the machine to Whic the resent invention is applied, some parts eing broken away to disclose others to the rear and some parts appearing in cross-section Fig. 6 is a detail sectional view taken substantially on the line 66 of Fig.. 5; Fig. 7 is a front elevation of indexing devices on the exterior of the machine; and Fig. 8 is a section on the line 8-8 of Fig. 7.

The present invention has to do particularly with that portion of the machine commonly termed the"printing section. In the regular Burroughs machine it is located at the rear and comprises suitable supporting side'plates, pivoted hammers 715 striking rearwardly, pivoted hammer-driving levers 716 carrying studs 75-3 engaging cam slots 7 in the hammers, springs 780 attached to said levers and tending to impel'them in a direction to deliverthe hammer blow, pivoted pivoted spring-actuated pawls 718 for lifting said latches, an oscillating bail carrying said pawls and composed of side arms 711 and a cross rod 704, and a restoring bail for the. levers 716, said bail comprising side arms 712 and a cross rod 709.

. The numeral 611 designates the usual rack latches 717 normally restraining said levers,

ranches 9 SUCCQSS registers with the numeral 4 on the plate H 'terior of the machine and inscribed with nu- I partaking of the excess movement necessary ing of excess movement. Conse stud 753 did not pass into the dwe l extension of the cam slot and the nose I) did not act against the edge a of the adjacent latch to the ri ht.

The following described means are em-- ployed for controlling the position of the sliding collar: Between collars g pinned to the aperturcd end of an irre ular-shaped link G, best seen in Fig. 5, said link at its left hand end being jointed to a crank arm 9 secured to the inner end of a rock shaft G (Fig. 1) which projects at the lower front part 0 the machine and which has aflixed to it a handle crank arm The latter is adapted to move over a segmental plate H secured on the eX- merals from 1 to 8 (Fig. 7 with any one of which numerals t pointed end of the arm 9 may register. The plate is'apertured as shown at h and the arm carries a knob 7L slidably mounted in a boss on said arm and thrust inwardly by a spring b (Fig. 8). The stem of this knob projects for engagement with one or another of the openings h. The arm 9 preferably carries a roller stud occupying an arc-shaped slot 71. in the plate H, for guiding purposes.

When the machine is to operate as normal '21. (3., without interruption of the hammer-tripping action the index arm or pointer 9 must be at the zero position, the stem of the knob h being engaged with the opening .7 furthest to the left and the pointer end of the arm g registering with the O inscri .tion on the plate. This means that the lin G and the rod f and consequently the collar 6 will all be in the'extreme positions to the left and the collar beyond the plane .of the first hammer-driving lever and so of course out of line with all the hammer-driving levers so that each can partake of movement sufiicient to trip the adjacent latch except of course the'lever associated with the units bank of keys. Should it be desired for example to establish a split between the fourth and fifth banks counting from the left the knob b will be drawn out and the arm 9 swung to. the right until the pointed end of the same as illustrated in Fig. 7. The release of the knob permits said arm to become interlocked with the plate at the proper adjustment to hold the coller 6 directly in line with the fourth hammer-driving lever counting from the left as illustrated in Fig. 5. The effect will be to prevent this lever from to trip the adjacent latch. Consequently the successive tripping will stop with the printing inthe fourth bank and assuming that no keys are depressed in any banks to l with' those banks will none of them be released as is illustrated in Fig. 5.

uently the i the right of the split the hammers associated 6'5 locating it by the inscriptions on the plate H. o

In order to assist t e user in properly indexing said arm a plate H (Fig. 2) is secured on the keyboard just below the amount keys and inscribed with numerals from 1 to 8 at points in median lines of the key banks or rows. The user 'will then determine by consulting the keyboard just where he desires to establish the spilt and will turn the handle crank arm until it registers with the numeral on the plate H corresponding with the numeral on the plate H, which numeral on the latter plate occurs in a median line of the banks of keys on opposite sides of the point where the split is desired. The plate H also has a O inscription located to indicate that when the handle crank arm is registering with the corresponding inscription on the plate H the keyboard can be used to'its full capacity in listing a single column of items.

While the above-described construction is well calculated to thoroughly fulfill the objects. primarily stated yet it is to be understood that this construction is susceptible of modification-without departure from the scope of the, present invention,

which can be carried out in various ways.
